1. osd: call on_new_interval on newly split child PG …

   We must call on_new_interval() on any interval change *and* on the
   creation of the PG.  Currently we call it from PG::init() and
   PG::start_peering_interval().  However, PG::split_into() did not
   do so for the child PG, which meant that the new child feature
   bits were not properly initialized and the bitwise/nibblewise
   debug bit was not correctly set.  That, in turn, could lead to
   various misbehaviors, the most obvious of which is scrub errors
   due to the sort order mismatch.
